Populate Reference Variable Based on Another Variable Selection in Service Catalog.

manishtyagi — Tue, 29 Jul 2025 17:31:42 GMT

Hi Community, I’m working on a Service Catalog item and need some help with a dynamic reference field. I have two variables Department and Doctor (Reference) When a specific department is selected, the Doctor variable should only display doctors who belong to that selected department. Can anyone guide me on how to achieve this? Should I use a Reference Qualifier or a Catalog Client Script?

Hi @manishtyagi

let's go with a reference qualifier on the Doctor variable.

Try something like:

javascript&colon; 'department=' + current.variables.department

EDIT: Please note that's automatica transcript, it shall be "javascrip t :" (no spaces) not javascript&colon;

Hi @manishtyagi,
----------------------------------------------------------------------------------------------------------------------------------------------------
Yes, you can definitely achieve this using Reference Qualifier (Advanced)
and you can write it like ->

javascript&colon; "u_department="+current.variables.department //replace the variable names with your original ones.

Now what it will do is that it will fetch the only doctors which belonged to the selected department
If you need further help do let me know.

@mayankkumar if it is a variable it will most likely not be "u_department", otherwise you wrote exactly what I did, so I must agree 😁💯

Hi @GlideFather,
I'm referring "u_department" to the field on the table from where doctor field is referenced not variable.
Why and where would I mention "u_department" as a variable? You can clearly see it's "current.variables.department" and "u_department" is assumed to be a field on referenced table. Maybe you're confused here. And I did not write what you wrote even I didn't know that you already posted a response here when I start writing this post has 0 responses
So, don't say that I wrote from your response.

@mayankkumar I see that it was posted at similar time, i meant it was both similar so i agree with you. Sorry if it turned out different way i have been multitasking.

it was just for the “u_”, otherwise agree in full but perhaps it will be completely different anyways, the author will know better

apologies 🙌

Hi @GlideFather,

No worries at all and really! I just meant to clarify things from a technical point of view. Nothing was meant to sound rude or personal😀.

Totally understand how things can come across differently. All good, and happy to collaborate anytime!

you can go through this -> Name conflicts may be introduced by new OOB fields if a custom field having same name has been created in Studio on same table hierarchy - Known Error
to understand more about "u_".
Feel free to correct me if I’m wrong.
